Federer should have come to net even more it really works for him. He also did not serve that well to begin and made way too many forehand errors. This seems to happen when he plays Novak lately. I still think Fed can potentially beat Djo in a 5 set match he just has to find a way to be more consistent. This was such a bummer. And yes as a previous poster mentioned in a few years Nole's play will begin to decline as well. We also have so many good younger players coming up we should see the old guard being tested even more. It's amazing Federer at this point in his career is still playing this well though, his willingness to add wrinkles to his game is fascinating. Also I get annoyed when he lets himself get in the chipping pattern to Novak's backhand he could go up the line with a chip a little bit more to keep him honest at least.
